Weird painting problem in a bedroom where a cable is below/buried in the plaster

[greeny]

We have just repainted our spare bedroom with our normal emulsion paint and noted a vertical streak from the ceiling down to a socket. We repainted over the streak but the streak reappeared.
I used my cable detector and established that the cable run was directly under the streak. The streak does not disappear when the paint dries
Weird...
An ideas please?

Different type of plaster used over chase that the paint reacts slightly different to? Presumably house has been rewired at some point or that socket was added at a later date to the house being built.

"clash" of new paint to old? It does happen with modern paints from time to time

Try covering the streak with 2 coats of a good old-fashioned oil based undercoat then use emulsion on top after it's dried properly.

Metal capping below a very thin skim of plaster ???

Metal capping is rusting slightly & the rust is leeching through the plaster.

or if you're flush, buy a aerosol "stain block" from a decent decorators supplier. it stops the stain penetrating the paint.

or paint it black

That's impressive!!

All I've got is a Kodak Brownie 127 (8 shots from a roll film) and a Kodak Brownie Starmite (12 shots from a roll of film and a built in flash wot you put flash bulbs into) a Zenith "B" 35 mm job and a Zenth "E" (like the "B" but with built-in exposure meter) and my Canon 30D.

I had a Canon 350D but Tidyboiler's No. 3 dowter is now the proud owner of it.

Nah! ........ It was Magnesium powder ........... NOT to be confused with the magnesia stuff wot you treat indigestion with!

Photographers flash powder was used for cameras, black powder would burn too slowly and not be bright enough. Not to be confused with flash powder as used in fireworks (aluminium based) that stuff would blow the photographer to pieces if you tried using it.

I thought I was pedantic.

Sir, I bow to your superior pedantry and am in awe.
